What’s your application for the PDR?
Let’s say you’re getting dialogue or reaction from someone on a ride at a theme park. If the ride has a lot of movement, you need to bury a device very deep on them.
Between that, the metal the ride is made of, and all the RF in the air the park uses for control and communications, it’s challenging to get signal from someone inside a ride.
I put the PDR on them, get a bit of them with the boom at the beginning and end, then let the PDR record and write time code and give it all to post when we’re done.
Between theme parks and aerospace shoots, has range ever been a challenge?
I did sound for a documentary at the Daytona International Speedway. It was about the Ford GT-40, the car that beat Ferrari at LeMans. Did you ever see that movie with Matt Damon, Ford v. Ferrari? Well, this was a documentary about the same subject.
I was up in the stands with my SRc receivers and a bow-tie antenna, and production wanted in-car audio for a vehicle that had a bunch of GoPro cameras on it. When the car is on the far side of the track, it’s almost a mile away, and there’s a building in between where they have the media centre.
I affixed an SMQV transmitter where the A-pillar of the car meets the dashboard and pumped it up to 250 milliwatts [output power]. Even when the car was at its farthest point away from me, and even when it was blocked by the building, I had clean audio that didn’t degrade even when the RF meter dropped to one bar.
I took some phone video switching between the car and my receiver and people couldn’t believe it. This was the first firmware version for the SMQV, no less.
Another occasion where the SMQV saved the day was a production involving a motor glider, which is a glider airplane that has a small engine and propeller as a backup. They wanted conversation inside the aircraft and asked me to put a field recorder in there — this was before the PDR was made, by the way. I told them, “No way. You’re going to hear nothing but noise.”
Instead, I miked the pilot and passenger with DPA 4071s, which have excellent background rejection, and once again used SMQVs at 250 milliwatts.
My receivers were UCR411a. With the glider about 2,000 feet up, we got crystal-clear audio. I played it back for the talent when they got back on the ground, and they were blown away. They could hear each other on the playback better than when they were originally talking!
